Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for obtaining trimmed image data when performing color separation of various originals using a scanner, particularly a layout scanner.

(Technical background) In recent years, along with the color separation of manuscripts using scanners,
Layout scanners that synthesize image data for one page of printed matter through computer processing are used in the field of printing plate making. This layout scanner is a scanner connected to a computer with a page editing function. Image data captured by the scanner is fed to the computer, and after processing such as layout, it is output to the scanner. be.

FIG. 14 is a schematic diagram showing the configuration of a general layout scanner, in which 160 is a layout section, 170 is a tablet digitizer, and 180 is a layout section.
is the Sukiyana club. As shown in the figure, the layout section 160 includes a computer 160, memories 162 and 163 connected thereto, and a display 16.
4. Joystick 165 and keyboard 16
Consisting of 6 tablet digitizers 170
consists of a cursor 171 and an input surface 172, and the input surface 172 has a mount area 173 and a menu area 17.
4 is set. The scanner section 180 is composed of an input drum 181, an output drum 182, and interfaces 185 and 186, and the interfaces 185 and 186 are connected to the computer 161. Note that the computer 161 includes an input computer, a layout computer, and an output computer (all not shown).

In this layout scanner, editing work of image data is performed in the following manner based on various manuscripts, layout specification sheets, and other instructions. First, a document is pasted on the input drum 181 of the scanner section 180 at an angle specified by the layout specification sheet, and the image data of the document is transferred to the computer 1 via the interface 185.
61 input computer (not shown),
It is stored in memory 162. Image data is imported from the original according to the magnification ratio indicated on the layout designation paper (not shown) for an area slightly larger than the actual trimming range based on the layout designation paper (not shown), and is later imported into the layout computer of the computer 161 (not shown). (not shown) for precise trimming.

The memory 162 in which image data has been written is separated from the input computer and connected to the layout computer. This will cause display 16
4 displays image data written in the memory 162. The operator observes this displayed image and moves the cursor by operating the joy stick 165 while referring to the layout designation sheet to designate the trimming range, the position of the screen cover, etc. Further, the keyboard 166 is used to specify the printing surface color, halftone percentage, etc.

Data that has been layout processed according to these specifications is written to the memory 163, so after the writing is completed, the memory 163 is disconnected from the layout computer and connected to an output computer (not shown) of the computer 161. As a result, the data in the memory 163 is taken out via the output computer and interface 186, and the trimmed and laid out image is output onto the film set on the output drum 182 of the scanner section 180.

Furthermore, the above operations performed using the joystick 165 and the keyboard 166 can also be performed by operating the tablet digitizer 170. That is, the tablet digitizer 170
Set the above-mentioned layout designation paper on the mount area 173 of
All you have to do is select and input the various menus set in 4.

Here, the input drum 181 of the scanner section 180
When importing image data of a document from the input drum 1, first place the document at the angle specified on the layout paper.
It is necessary to paste it to 81. The pasting work of this manuscript is carried out by the operator based on visual estimation. That is, the inclination angle of the figure on which the layout designation paper is drawn is measured with a protractor, and based on this measurement value, the angle of the document is confirmed using a protractor or the like and is pasted on the input drum. Therefore, there has been a problem that not only the work is complicated, but also the manuscript cannot be pasted at an accurate angle.
In order to improve the work of pasting documents onto the scanner's input drum, we have developed a special device that uses a magnification measuring machine with a document projection function to measure the magnification and output the document angle pasting gauge. This invention has been proposed by the present applicant as the invention of Application No. 162108/1983.

Next, in layout work using the computer 161, it is necessary to accurately trim the captured image data. Since this trimming work is performed by displaying the image on the display 164 and operating the joy stick 165, the position of the trimming range tends to be inaccurate, which not only requires skill but also requires the use of the computer 161 for a long time. There was a problem that the expensive layout scanner could not be used efficiently.

Therefore, in order to improve this work, the above-mentioned original angle pasting gauge is used to define the pasting position of the original, and position data regarding the edge corner points of the original are established in advance, and the tablet shown in FIG. Japanese Patent Application No. 59-141324 discloses a method of reading cropped image data by supplying position data or magnification data necessary for calculating the trimming range of the document to an input computer of a layout scanner using a digitizer 170. It is proposed by the applicant as an invention.

However, in the invention of Japanese Patent Application No. 59-141324, since only one set of orthogonal lines is drawn at a predetermined position on the original angle pasting gauge, it is not possible to set multiple originals to the input of the scanner at the same time. Moreover, since the magnification and angle measurement of the document and the data input work using the tablet digitizer 170 are performed separately, there have been problems in that work efficiency is low and the precision of the trimming range data is also poor.

(Object of the Invention) The present invention has been made in view of the above-mentioned points, and it is possible to input position data for calculating cropping range data at the same time as measuring the magnification and angle of the original, and to scan multiple originals. It is an object of the present invention to provide a device which can be set on an input drum of the present invention and read trimmed image data.

(Summary of the Invention) To achieve this objective, the present invention provides a magnification measuring machine that measures the magnification of the original by projecting the original into a specified size, and a magnification measuring machine that measures the magnification of the original by projecting the original into a specified size, and a data tablet into which position data indicating the trimming range of the projected document are input, and calculations are performed based on the magnification data from the magnification measuring device and the position data from the data tablet to determine the document pasting line and an arithmetic control device that calculates data of a trimming range; a storage device that stores output position data for a plurality of documents; and a document pasting line sheet for a plurality of document documents based on the calculation results and output position data of the arithmetic and control device. and an output device that outputs an image to the trimming area based on the trimming range data, with the sheet on which the original is pasted according to the original pasting line output on the sheet set at a predetermined position on the input drum of the scanner. A trimming device for printing plate making is provided, which is equipped with a control device that directly captures trimmed image data from a document.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an apparatus showing an embodiment of the present invention. In the figure, A ₁ is a document pasting sheet creating device, and A ₂ is a layout scanner. Second

Reference numeral denotes a layout designation sheet, I represents a projected image of the original set in the original holder 5, and W represents a sheet on which original pasting lines, trimming lines, etc. are drawn.

The projection lens 4, document holder 5, and lamp house 6 are held together by the support 3, and the magnification measurement is performed using the surface of the designated layout paper B placed on the surface of the workbench 2 as the projection surface of the document image. A document placed in a document holder 5 is illuminated by a light source provided in a lamp house 6 through a suitable condenser lens, and a projected image I of the image is displayed. It is designed to be projected onto the surface of designated paper B.

Furthermore, the projection lens 4, document holder 5, and lamp house 6 are configured to be movable up and down along the support 3, and can be moved up and down by operating a switch on the operation control panel 7. A projection image I obtained by reducing or enlarging the image to an arbitrary size over a predetermined range can be formed on the surface of the layout designated paper B. Then, at this time, the distance between the projection lens 4 and the layout designation sheet B is taken in by a linear encoder or the like, and the magnification is calculated through arithmetic processing and displayed on the magnification display 8.

Therefore, set the transparent original in the original holder 5,
If the projected image I is matched with the figure drawn on the layout designation paper B, the magnification is automatically displayed on the magnification display 8, and the magnification measurement can be completed. Note that such an automatic magnification measuring machine is well known.

Also, magnification measuring device 1 and data tablet 1
The data given from 0 is input to the arithmetic and control device 20 via a signal input section (not shown), but at this time, data acquisition and the start of arithmetic processing by the arithmetic and control device 20 are performed by the operation control panel. It is controlled by the numeric keypad, push button switch, keyboard 21, etc. provided in 7.
A drive signal is output to the XY plotter 30, a display signal is output to the angle display 9 and the magnification display 8, and the like.

The layout scanner A ₂ is composed of a scanner section 180 and a layout section 160 of the apparatus shown in FIG.
0, a floppy disk device 167 is connected to a computer 161, and 187 in FIG. 1 is a scanning head.

The linear encoder 183 detects the position of the scanning head 187 and generates position data P _x representing the axial position of the drum 181. The rotary encoder 184 detects the position of the scanning head 187 in the axial direction of the drum 181. It detects the position where the sensor is located and generates position data _Py corresponding to the detected position.

The floppy disk device 167 is for receiving data stored in the floppy disk device 23 of the original pasting sheet creating device _A1 , and the computer 161 is used to receive data stored in the floppy disk device 23 of the original pasting sheet creating device A1.
The document trimming range data etc. are read from 67, and the interface 185 is controlled to take in the trimmed image data V.

Next, the operation of the apparatus shown in FIG. 1 will be explained.

FIG. 3 is an explanatory diagram showing the measurement procedure in the original pasting sheet producing apparatus _A1 .

First, after setting the layout designation paper B (or a copy thereof) on the data tablet 10 on the workbench 2 (S1), a document such as a color film is set on the document holder 5, and in S2, the data tablet 10 on the workbench 2 is set. An image I of the original is projected onto the surface of the layout designation sheet B set on the sheet.

Next, after inputting the document number using the numeric keypad or keyboard 21 provided on the scanning control panel 7, the user operates the magnification adjustment switch provided on the operation control panel 7 to input the document number drawn on the layout designated paper B. An attempt is made to match the pattern of the original image I with the layout designation graphic. Incidentally, the matching of the positions at this time is performed by moving the layout designation paper B on the workbench 2.

Thereafter, when the magnification display switch on the operation control panel 7 is operated, the magnification at that time is displayed on the magnification display 8 and the magnification data is taken into the arithmetic and control unit 20 at step S4.

As already explained, the above operation is almost the same as in the case of a well-known magnification measuring machine, and the following operation is not necessary for documents that do not require angle setting or trimming range setting.

Next, various positional data on the layout designation sheet B are inputted in S5.

FIG. 4 is an explanatory diagram of input points on the data tablet 10. In the figure, a layout designation paper B is placed on a data tablet 10 provided on a workbench 2, and a printing plate line H forming a rectangle and a figure E for layout designation are drawn on the layout designation paper B. It is.
The projected image I is projected so as to match the figure E.

First, the position data of two points P1 and P2 on the printing plate line H drawn on the layout designation sheet B are inputted using the cursor 11. This plate surface line H corresponds to a reference line when pasting a document onto a disassembly drum of a scanner. Next, use the cursor 11 to input the position data of rectangular vertices R1, R2, R3, and R4 that form the projection image I, and further input the position data of the rectangular vertices Q1, Q2 that indicate the trimming range in the projection image I. ,Q3,Q
Input the position data of 4 using the cursor 11. These position data are taken into the arithmetic and control unit 20 by operating the operation switch on the operation control panel 7 or the keyboard 21.

When the positional data on the layout designation paper B is thus input, at this point the arithmetic and control unit 20 starts processing the positional data and the magnification data, and calculates the pasting line data and trimming range data of the original at step S6. Next, this document is input to the output position data on the sheet W of the paste line and the trimming range, and is taken into the arithmetic and control unit 20.
7. Then, various data taken into the arithmetic and control unit 20 are stored in the floppy disk device 23 at S8. At this time, the stored position data of the pasting line and trimming range of the original document takes into consideration the output position on the sheet W.

Here, when the gauge output switch on the operation control panel 7 or the keyboard 21 is operated, the data from the memory is sent to the control circuit of the XY plotter 30, which starts the graphic output operation by the XY plotter 30, and pastes the original. In step S9, a hard copy with a line and a figure indicating the trimming range drawn at the designated position is completed.

After this, when performing the magnification measurement work for the next document, the process returns from step S10 to step S2, and the operations up to step S9 are performed. In this case, when inputting the output position data in step S7, since the sheet W is drawn with a figure showing the pasting lines and trimming lines of the original that have been input up to the previous operation, it is easy to refer to this figure. Desired output position data can be input into the .

In this way, when the series of operations such as repeating the magnification measurement work of a predetermined document is completed, or when there is no more space for figures that can be drawn on the sheet W in step S10, an end operation is performed S10.

FIG. 5 is an explanatory diagram showing the positional relationship of each point input from the data tablet 10 in step S5. Based on the diagram, calculation of the pasting line data and trimming range data of the original in step S6 is explained in detail. explain.

Coordinates P1 (a, b), P2 (c, d) of two points P1, P2 on the printing plate line H in the X-Y coordinates shown in the figure
Then, the inclination θ of the plane line H with respect to the coordinate axis X is tanθ=d−b/c−a.

Here, the origin is P0 (w, z), and the printing plate line H
If the new coordinates whose coordinate axes are the lines perpendicular to these are x-y, then the coordinate transformation formula from the X-Y coordinates to the x-y coordinates is as follows.

X=x cosθ+y sinθ+w Y=-x sinθ+y cosθ+z Than this x=(X-w)cosθ+(z-Y)sinθ y=(X-w)sinθ+(Y-z)cosθ becomes.

Also, from the formula, sinθ and cosθ are sinθ=|d-b|/√(c-a) ² +(d-b) ² cosθ=|c-a|/√(c-a) ² +(d-b ) ²
Therefore, on the data tablet 10,
The coordinates of an arbitrary point input as Y coordinates are replaced by coordinate values on the xy coordinates with the printing surface line H as a reference based on the formula. For example, if the X-Y coordinate values of point R1 are (XR1, YR1, and the x-y coordinate values are (xR1, yR1), then xR1 = (XR1 - w) | c - a | /√ (c - a) ² + ( d-
b) ² + (z−YR1｜d−b|/√(c−a) ² +(d−b
) ² yR1=(XR1-w)｜d-b|/√(c-a) ² +(d-
b) ² + (YR1-w) | c-a | /√ (c-a) ² + (d-b
) becomes ² . Similarly, all points R2 to R4 and Q1 to Q4 are obtained in xy coordinates.

Next, drawing coordinate values for drawing with the XY plotter 30 are calculated from these coordinate values.

If the magnification obtained in the magnification measurement work is multiplied by m, the coordinate values obtained as a result of the above calculation are (x, y), and the drawing coordinate values are (Dx, Dy), then Dx = (1/m) x Dy = (1/m)y.

Therefore, from the formula, XY plotter 3
A drawing coordinate value that is drawn at 0 will be obtained.

FIGS. 6, 7, and 8 show examples of inputting output position data in step S7 of FIG. 3, and each example will be explained based on the figures.

FIG. 6 shows an example of inputting an output device that displays original pasting lines and trimming lines on the display 22. In the figure, 250 indicates the outer frame of the sheet set on the XY plotter 30, and FN
is the manuscript number, and SI is the size of the above sheet. As shown in the figure, there is an outer frame 2 on the display screen of the display 22.
50 is displayed, and a predetermined position inside the outer frame 250 is displayed.
Outline part 251 of the document and trimming line 252 at a0
A figure A consisting of
SI is displayed.

The outer frame 250 is displayed by inputting the size of the sheet W when the layout specified paper is set in step S1, but the sheet size can be input by directly inputting the size itself from the keyboard 21. Alternatively, this can be done by inputting preset numbers and symbols, or the target scanner and drum type. This input sheet size is then taken into the arithmetic and control unit 20. Note that if the size itself is not input, the output size corresponding to the input number etc. is stored in advance in the memory 23 of the arithmetic and control unit 20. The contour line 251 is displayed based on the document pasting line data calculated in step S6, and the trimming line 252 is displayed based on the document pasting line data calculated in step S6.
This is displayed based on the trimming range data calculated in step 6. Further, the figure A displayed on the display 22 can be moved arbitrarily within the outer frame 250 by operating a cursor movement key (not shown) provided on the keyboard 21. Therefore, by operating the keyboard 21 and moving the figure A to a desired position, the output position data in step S7 is input. This movement of figure A is performed, for example, by moving figure A to position a1 indicated by the broken line in FIG. Note that the predetermined position a0 is not limited to the lower right corner as shown in the figure, but can be set arbitrarily.

In addition, since the outline, trimming line, etc. of the document whose output position has been inputted up to the previous operation are displayed on the display 22, when inputting the output position data in step S7, the figure displayed at position a0 is may be moved to a desired position by referring to these display figures into which output position data has already been input.

Figure 7 shows an XY with a digitizer that allows you to directly input the output position instead of the XY plotter 30 shown in Figure 1.
This shows an example of using a plotter. Figure a is an external view of the digitizer

This XY plotter with digitizer 40 is connected to an arithmetic and control unit 20 shown in FIG. Here, step S7 is performed based on FIG. 8b.
The output position data input will be explained below.

As shown in the figure, there is a sheet W on the digitizer surface 42.
is placed on the sheet W, and a figure SB consisting of a contour line 261 indicating a document pasting line and a trimming line 262 has already been drawn at position b1 at the upper left corner of the sheet W.
To input the output position in step S7, use the cursor 43.
The input information is input by moving the digitizer surface 42 to indicate a desired position on the digitizer surface 42. For example, if point b2 is specified with the cursor 43 as shown in the figure, point b
A figure consisting of a contour line and a trimming line, such as figure SB, is drawn by the pen 44 with 2 at the center.

FIG. 8 shows an example of specifying a plurality of pre-stored output positions of the XY plotter 30, and FIG.

As shown in the figure, a sheet W is placed on the board 31 of the XY plotter 30, and a figure SB consisting of a contour line 261 indicating a document pasting line and a trimming line has already been drawn at position c1 at the upper left corner of the sheet W. There is.
Here, the output position of the XY plotter 30 is input as follows. First, the transparent film 270 is placed on the sheet W on the board 31. Grid lines 273 are drawn on the transparent film 270, and intersection points of the grid lines 273 are marked with intersection points No. 274. The transparent film 270 and the board 31 are positioned by pins 32, 32 provided at one end of the board 31 and holes 27 provided at one end of the transparent film 270.
1,271 is inserted. Then,
Intersection No. 274 near the desired output position c2.
is selected and input using the numeric keypad or keyboard 21 provided on the operation control panel 7. This means that the output position has been input in step S7.

FIG. 8b is a table showing the relationship between the intersection point No. 274 and the coordinate values on the XY plotter 30. As shown in the figure, the table 280 shows each intersection point No. 274 when the transparent film 270 is set on the board 31. The X coordinate of the output position of the XY plotter 30 corresponding to .274,
The Y coordinate is set. This table 280 is stored in advance in the memory of the arithmetic and control unit 20.

FIGS. 9a and 9b are explanatory diagrams showing examples in which original pasting lines and trimming lines output in step S9 are drawn on various sheets.

FIG. 9a shows an example of drawing on a transparent sheet 100. In the figure, at one end of the transparent sheet 100, a reference line 101a corresponding to the printing plate line H and a line 101b orthogonal to the reference line 101b are drawn, as well as a document number 100N and a magnification value 100m. Transparent sheet 100
A rectangular original pasting line 102 is drawn in the center of the document pasting line 102, and a rectangular trimming line 103 indicating a trimming range is drawn inside the original pasting line 102.

2 is drawn, but the trimming line 203 is drawn with each side of the rectangle extended to the outside of the document pasting line 202. This is opaque sheet 200
This is because the cut out original is set after it is cut and cut out along the original pasting line 202.

FIG. 10 is an explanatory diagram showing an example in which original pasting lines and trimming lines output in step S9 for a plurality of originals are drawn on a transparent sheet. As shown in the figure, a reference line 301a and a line 301b perpendicular to the reference line 301a are drawn at one end of the sheet W, and the original pasting line 302 and trimming line 303 of each original are drawn at desired positions. Document No. 300N and magnification value 300m are drawn near the trimming line.

Ta and Tb are perpendicular to each other and provided by a suitable method such as paint. As shown in the figure, the sheet W is first aligned with the reference lines 301a and 301b on the drum 181.
One end of the input drum 18 matches Ta and Tb.
It is fixed to the circumferential surface of 1 using tape or the like. Then, desired documents F1 to F4 are placed on the sheet W and the input drum 1 along the outline of the document drawn on the sheet W.
The other end of the sheet W is fixed to the circumferential surface of the drum 181 with tape or the like, and the setting of the original onto the input drum 181 is completed.

FIG. 11 is a flowchart showing the operation of the layout scanner _A2 , and the following describes how to capture image data of a document based on the figure.

First, as shown in FIG. 12, after a predetermined original is set on the input drum 181 via the pasting sheet W (S20), it is stored in the floppy disk device 23 of the original pasting sheet creating device _A1 by the floppy disk device 167. In step S21, the stored data is read. This data represents the document number, magnification value, document outline, trimming line, drawing position, etc. drawn on the sheet W. Next, when the number of the document into which image data is to be imported is input, the process proceeds to step S22.
Based on the data read in step S21, the computer 161 calculates position data of the trimming range of the document using the reference lines Ta and Tb of the input drum 181 as coordinate axes in step S23. Thereafter, the operation head 187 of the scanner section 180 starts reading the image data of the original, and only the data of the image within the trimming range is read based on the data calculated in step S23. S25 is stored in the memory 162 via 161.

FIG. 13 is an explanatory diagram showing only the trimming range position calculated in step S23, and the calculation of the trimming range data in step S23 will be explained based on this figure and FIG. As shown,
Let K be the figure showing the trimming range of the document F1 set on the input drum 181, its two opposing vertices be q1 and q3, the intersection of the reference lines Ta and Tb be p, and the position coordinates of the input drum 181 be q1, respectively.
(xq1, yq1, q3(xq3, yq3 and p(xp, yp)
shall be. These points q1, q3, and p correspond to points Q1, Q3, and P0 shown in FIG. 5, respectively. Now, the position data of points Q1 and Q3 are expressed as coordinate values (xQ1, yQ1, (xQ3, yQ3) on the x-y coordinates whose origin is point P0 shown in Fig. 5, and the magnification value is m
Then, the relationship between the coordinate values of each point above is as follows.

xQ1=m(xq1−xp) − yQ1=m(yq1−yp) − xQ3=m(xq3−xp) − yQ3=m(yq3−yp) − Here, the coordinate values of points Q1 and Q3 are (xQ1 ,
yQ1, (xQ3, yQ3 are calculated in step S6 of FIG. 3, these coordinate values are given to the computer 161 in step S21 of FIG. 11, and the point p is
Since the coordinate values (xp, yp) are given to the computer 161 as constants, the above ~
Point q required to specify the trimming range K
Position data representing 1, q3 xq1, yq1, xq3,
yq3 can be easily calculated.

Note that in step S24 of FIG.
Position data representing 1, q3 xq1, yq1, xq3, yq3
Various methods can be considered for reading image data only from the trimming range K.
For example, the position of the scanning head 187 in the scanning direction (sub-scanning direction) is detected by the linear encoder 183, and data P _x from this and data P _y from the rotary encoder 184 are used to The scanning head 18 uses a gate that opens only until P _x exceeds position data xq1 and reaches xq3, and a gate that opens only until data P _y exceeds position data yq1 and reaches yq3.
It is sufficient to gate the image data V from 7.

All the image data of originals F1 to F4 set on the input drum 181 in this way are stored in the memory 16.
2, the image data is laid out, corrected, changed, etc., and the laid out image data is outputted to the exposed film set on the output drum 182 via the interface 186. The exposed film on which an image has been formed is used as a film original in subsequent steps.

Note that in preparation for changing or modifying the trimming range of image data during layout processing by the computer 161, image data in a range slightly larger than the trimming range K may be imported to leave room for modification or modification.

(Effects of the Invention) As described above, in the apparatus of the present invention, the magnification data of the original is measured by the magnification measuring device, and the position data of the original projected from the data tablet and the position indicating the trimming range of the projected original are used. Data is input, and based on these data, the arithmetic and control unit calculates data on the document pasting line and the trimming range. Then, based on the data on the document pasting line and the trimming range, the output device outputs the trimming line on the sheet, and the scanner control device controls the image capture range. Further, the sheet on which the original is pasted in accordance with the original pasting line outputted on the sheet is set at a predetermined position on the input drum of the scanner, and the image data of the original is input.

Therefore, according to the present invention, by setting a sheet with a plurality of originals pasted on the input drum along the original pasting line, a plurality of originals are set on the input drum of the scanner. It is possible to greatly improve the efficiency of document pasting lines on the input drum of the scanner. In addition, since it is possible to read accurate cropped image data based on the data of the trimming range from the scanner, you can quickly set the trimming range without having to do the complicated setting of the trimming range on the display. It also has the effect of being accurate.

As a result, the operating efficiency of the layout scanner can be significantly improved.
